That's interesting, thanks Paul. So it must be a problem with my XP machine/setup then. I'll also try DOpus to see if that helps.
Did you try with both an Amiga CDROM and a PC CDROM BTW? You might need to add the PC driver to read PC CDROM's but Amiga CDROMS *should* work ok without it (see Thomas's comments above).
It's good to know that it can work though, thanks again
